In reply to the discussion: A CAR that runs on fuel made from CO2 removed from the Atmosphere creating a carbon neutral loop! [View all]NYC_SKP
(68,644 posts)1. If it sounds too good to be true, it's probably not true.
Not entirely true, at least.
For starters, electrolysis requires electrical power, that's not free. Sure it could be wind or solar, fine.
Second, this just creates a replacement for existing liquid fuels to be used in internal combustion engines or turbines, so I don't think it's going to be as efficient as electric vehicles.
And I doubt that it's any more carbon neutral than wind/solar derived electron.
Still, research is fun!

OP
I understood they would get Hydrogen from the electrolysis, to mix with CO2 they got from air.

People need to re-read references on perpetual motion machines whenever an idea like this comes up

Cue the climate doomer skeptics(of mitigation prospects, that is) yelling, "impossible!".

No, it cannot work. You cannot violate the second law of thermodynamics. See my comment above. nt

I agree, I just meant there's nothing here that on its face goes against Boltzmann

More interesting for air transport, I'd say; we had a thread on the company last year

The C=O bond in CO2 is extremely stable and requires substantial energy to break

There would be nothing like the perpetual motion machine to stir one's interests but for one thing.

Not energy efficient, but has the advantage of working within our current infrastructure.
